HENRY I. LEA, OF PITTSBURG, PENNSYLVANIA, ASSIGNOR, BY'MESNEASSIGNMENTS, TO THE COLONIAL TRUST COMPANY, TRUSTEE, 0F PITTSBURG,PENNSYLVANIA, A

CORPORATION OF PENNSYLVANIA.

To all 'whom t may concern:

Be it known that I, HENRY I. LEA, a citizen of the United States, and aresident of Pittsburg, in the county of Allegheny and State ofPennsylvania, have made a new and useful Invention in Gas-Producers, ofwhich the following is a specification.

This invention relates to gas producers and more particularly to meansfor delivering steam or water vapor to the air entering the producer.

The object of the invent-ion is to produce means for utilizing thesensible heat of the outgoing gases to vaporize the water which is to becarried into the producer by the air.

In the drawing: Figure 1 is a sectional elevation of a portion of theproducer provided with an embodiment of my invention. Fig. 2 is a planview of one form of my invention. Fig. 3 is a sectional view on the line3 3 of Fig. 2.

The apparatus illustrated is in effect a boiler comprising a spiralpassage which is located at the top of the gas generating chamber of theproducer and through which the air delivered to the producer is causedto pass. Water is delivered to the spiralv passage by suitable means,employing a suitable valve construction if desired.

Referring to the drawings: The gas generating chamber 4 of the gasproducer is inclosed within a shell portion 5 and is provided near thetop with a gas otake port 6. A Hash boiler 7 which embodies my inventionis mounted upon the top of the gas generating chamber adjacent to thegas otake port 6, and comprises a portion 8 which is provided withspiral groove 9 and a portion 10 which coperates with the portion S toclose the top portion of the groove 9 and thereby form a spiral passage.The top portion 10 forms the top of the gas generating chamber. A fuelhopper may be arranged above the producer which may have its dischargeend through the opening 11 of the flash boiler 7. The portion 8 isprovided with a flanged part 12 which communicates with the outerSpecification of Letters Patent.

extremity of the groove 9 and which is adapted to be connected to a pipe13 which delivers the saturated air to the producer below the fuel bedcontained in the gas generating chamber.

Water may be supplied to the groove 9 through a pipe 14 communicatingwith a suitable source of supply and said water will enter the groove 9near its inner end, and in flowing in t-he spiral path to the deepestpart of the groove, which is adjacent to the outlet port 12, it isvaporized by the sensible heat of the outgoing gases. Air may enter thegroove through the pipe 15 and become heated by the sensible heat of thegases, whereby its vapor carrying capacity is increased.

lhat I claim and desire to secure by Letters Patent is:

1. A steam or vapor generator comprising a portion provided with aspiral groove increasing in depth and sectional area in the direction ofthe steam outlet port, a member coperating therewith to close saidgroove and thereby form an inclosed spiral passage, means for admittingwater in regulable amounts to said passage and a vapor outlet portcommunicating with said passage.

2. A steam or vapor generator comprising4 a spiral groove increasing indepth and cross sectional area from the inlet port to the outlet port,in combination with an inlet port and an outlet port, and means forintroducing air into said passage.

3. A steam or vapor generator comprising a spiral groove provided withan inlet port and an `outlet port and increasing in .cross-sectionalarea from the inlet port to the outlet port.

4. A steam or vapor generator comprising a portion provided with aspiral groove increasing in depth and cross-sectional area in thedirection of the steam or vapor outlet port and a member cooperatingtherewith to close said groove and thereby form an inclosed spiralpassage provided with an inlet port and an outlet port.
